1.Design a 3-bit counter with a Gray code sequence. (A Gray code is a binary number system where two successive values differ in only one digit; it was originally designed to reduce error in counting especially in mechanical industry). The following table represent a 3 bit Gray code and its equivalent in decimal. Decimal Gray code 0 001 011 010 110 2 4 101 100 The highlighted digits are the ones that changed (counting up). The Gray code "wraps around:" When rolling over from 0 to 7, only one digit changes. The counter should count in Gray code sequence as illustrated in the above table (e.&000> 001 >011 and so on). You should follow the following design procedure as follow: Draw the state diagram Present & Next states table Transition table Excitation table Boolean expression of each Js and Ks K-map Simplified expression of Js and Ks Draw the logic.diagram of the counter
